I am not responsible for what my mind comes up with after midnight.

Borrowing from HP: PoA with a ~romantic twist
- A young woman (Character A) gets trapped in her ~domestic animal~ animagus form and ends up as a pet for another struggling young woman (Character B). After noticing romance starting to bloom between Character B and a potential suitor, Character A goes out of her way to make the two cross paths whenever in public together. Would work great if the animagus form was something small so she could be a stowaway.
ALTERNATIVELY
- Character A falls in love with Character B and enlists their animagus or metamorphagus friend (Character C) to spy on Character B to see if their feelings are returned. All the better if Character C is really suspicious, very straightforward, or gets caught way too easily to where it makes things #awkward.
